IMPROVEM ENT IN WOOD H EATlNG-STOVES.

Specification forming part of Letters Patent No. 199,446, dated January22, 1878; application filed August 31, 1877.

To all whom 'it may concern:

Be it known that I, SHERMAN S. JEWETT, of the city of Buffalo, in. thecounty of Erie and State of New York, have invented an Improvement inWood Heating-Stoves, which improvement is fully set forth in thefollowing specification, reference being had to the accompanyingdrawings, in which- Figure 1 is a vertical central section from front torear. Fig. 2 is a horizontal section above the top of the detachableflue-plate, the bottom flue-strips being shown in dotted lines; and Fig.3 is a view of the removable plate, showing its rear surface, the hooksthereon, and the lip at the bottom.

The downward-flue heating-stove for wood, from its construction,necessitates the action of the flame from the fuel upon both sides ofthe plate forming the rear of the fire-chamber; and to protect the samefrom the effects of the heat, I construct an adjustable back fire-plate,G, as shown by the dotted lines a a in Fig. 1, and by the drawings,Figs. 2 and 3, furnished with the hooks A, which hang onto the catches Band are secured at the-bottom by the lip O. The protection afforded bythe aid of the adjustable fire-back prevents the burning out of theplate E, forming the rear of the fire-chamber, and when the fire-back isrendered use less it can be easily replaced by a new one.- Thisadjustable plate also forms the front Wall of the flue D, so that itreceives the most intense action of the flame; whereas if the rear plateE were constructed in one piece with the flue-hole F, as shown above thedotted lines a 0, even if protected with a fire-plate, the action of theheat would soon cause it to crack, which would necessitate thedismounting of the whole stove in order to remove the damaged plate.

I do not confine myself to any particular system of flues, as myinvention is equally important to any system of flues.

I do not claim, broadly, the fire-back.

What I claim, and desire to secure by Letters Patent, is-

The detachable back fire-plate (l, a portion of which forms the frontwall of the rear flue or flues, in combination with the interior backplate E, in connection with a divingflue heating-stove, substantially asand for the purposes herein described and shown.
